Note: this is for Windows 7 64-bit users only, who have Intel WiFi N cards in their laptops. If you experience any of these issues noted below while using a 32-bit system, try the workaround noted. If it helps, post here and let me know.

I have identified an issue with the Intel WiFi Link 5000-series cards (5100 and 5300), and possibly the 4965AGN card under Windows 7 64-bit.

ddggttff3 has noted his Intel WiFi Link 1000 has suffered from the same symptoms, therefore this may apply to the Intel WiFi 1000 and 6000 series (6100 & 6300) as well.

I'm unsure whether this may affect the 5150/5350/6150/6350 WiMAX cards, as they use a different driver (I don't think they're popular cards anyway).

Symptoms

* During transfers or while idle, you may be disconnected from your access point.
* During transfers or while idle, you may experience extremely low download speeds.
* During transfers or while idle, you may experience websites loading very slowly.
* During transfers or while idle, you may experience high latency and ping timeouts to servers or your DD-WRT gateway. (Not DD-WRT specific)

Description

A problem is present in the driver which causes the symptoms noted above to occur, in Windows 7 64-bit only. Upon contacting Intel with the information gathered, they denied any issues with the drivers and claimed they are unable to talk to me due to the fact that I violated FCC regulations.

Workaround

Open Device Manager (located in the Control Panel). Expand the Network Adapters tree and right click on your Intel WiFi adapter. Disable. Right click again and enable. Reconnect to your access point (if Windows 7 does not automatically reconnect).

Resolution

Intel has released driver 13.1.1.1 for all affected Intel WiFi based cards. I can confirm that this driver has resolved all issues with my WiFi Link 5300.

Here is a direct download link to new drivers. Under "Select a Family", choose Wireless Networking. Then, under, "Select a Line", choose Intel WiFi Products. Then, under "Select a Product", choose the current WiFi card you have. You'll be prompted to choose to either get support or download drivers, click on Download Drivers. When you get there, you'll be asked to select your operating system. Choose Windows 7 (doesn't matter what flavor, the drivers are the same) and either 32 or 64-bit. Then choose "Drivers". If you scroll down you'll be given an option of different drivers to download.

If you want the drivers only, choose: Intel® PRO/​Wireless and WiFi Link Drivers-​Only for Windows 7 64-bit*
If you want the drivers and the extra utilities (which are pretty much worthless) OR you want the Intel My WiFi Technology (make your computer an access point while retaining your wireless internet connection), choose: Intel® PROSet/​Wireless WiFi Connection Utility for Windows 7 64-​Bit*

Don't know what card you have? Open the Device Manager in the Control Panel, and expand the Network Adapters tree. There, you'll see something like "Intel WiFi Link ****", "Intel Wireless WiFi Link 4965", or "Intel Centrino...". This will be your adapter model.

I'm curious, what information did you gather and do you know what you did to violate FCC regulations (even though you're not regulated by them )?

I know there's been a few cases of people having these problems so it's good that you discovered this._________________Read the forum announcements thoroughly! Be cautious if you're inexperienced.

Just some test results I did (when it was most likely to occur, what was happening when it occurred, etc.

They claim that by installing my own wireless card (as approved by the laptop manufacturer) I violated FCC regulations. Funny enough, I don't live in the States (where FCC regulations are enforced) and it's not prohibited in Canada (as far as I know).

Thanks a TON for this tip! I have both the wifi 1000, and 5100 in the same laptop, and both lagged out on me aLOT, seems the driver fixed my issues!

Good to hear. I posted the same thing on the Intel Communities forum and it was quickly removed by a moderator & I got banned.

EDIT: This happens with the 1000 as well? Interesting...this may affect the 6100 and 6300 series as well (1000, 6100 and 6300 are very similar I believe). I've edited the original post to reflect your findings, thanks for this info.

Thanks for the sticky as well, hopefully this will help a lot of people out!

That's what I said to Intel. I asked him for the exact spot where it says it's prohibited (he couldn't provide it), and he refused to supply any qualifications (besides "I am certified to support all Intel Wireless products").

While I have nothing *directly* to contribute to the reported problem, I do believe you should report the company to the appropriate authorities. They are clearly lying and it would appear they are trying to cover up their sorry programming. Besides, saying you "violated" some rules with out sufficient justification is just poppycock. They know they cannot prove it, therefore they were trying to deflect the truth._________________E3000 22200M KongVPN K26

I doubt it would actually go anywhere. Intel is a massive company who have high powered lawyers on the payroll who are paid to deflect complaints such as these. What are the authorities going to do? Give them a slap on the wrist? Fine them? Ooooh, a fine. We'll have to pay using our billions of dollars in the bank. Oh no! We'll be broke after this fine! /sarcasm Unfortunately in today's world the best action you can take against a company is to vote with your wallet - don't buy their products anymore._________________Peacock Thread | Wireless Drops/Slow?

redhawk_________________I currently test dd-wrt on Asus, Buffalo, Linksys, and Netgear. Too many to list.

Looking for more test units (newer models) for the project...got a brick?...PM me to make a hardware donation. (USA) A donation is not a debricking service....it is a way to "Give back" to the dd-wrt project.

I do NOT provide personal assistance through chat or phone....so please don't ask.

I got Intel Wifi Link 5100 and its the best wificard i have ever seen/owned, the speed i got, around 4MB/s or 32Mbits with Linksys WRT54GL, the range, and the signal is incredible. So i cant really say that I've got any of these problems.

The drivers I'm using is 13.0.0.107, going to update them right after this post to the newest, Thanks for the link.

And of course DD-WRT on the WRT54GL and using Windows 7 64-bit or ubuntu, same results. Mostly use windows.

Interesting, I've definitely had this problem with the 1000. I worked around it by manually setting the channel and width on the router. Things have been much better since. Gonna try the new driver and see if I can kill that workaround.

EDIT: Hmm, still having problems connecting over 65Mbps unless I set the channel and channel width manually.

Please point us to where the FCC would try to impose an absurd rule upon consumers that will neither know nor care about such a rule. Manufacturers need to include the info, but after it's in consumers hands they'll do with it as they please as long as they don't change the radio output in a way that will violate regulations about interference._________________Read the forum announcements thoroughly!
